Pairing the Unifying receiver
The Unifying receiver is uniquely paired to your mice and keyboard. If you loose the original receiver, you can get another one for free from Logitech under warranty. However, the new receiver will need to be paired to your device using the Windows software. The software does not run under Wine and can't be used via a virtual machine.
There is a command line utility to add a device to a single Unifying receiver - it does not implement removing such pairing though. Read this online discussion carefully for source code and more details.
